This paper introduces contour-based three-dimensional terrain reconstruction algorithm. The three-dimensional data of discrete points are obtained by digitized contour lines. Delaunay density of discrete points is determined by the density of three-dimensional of contour line points. Three-dimensional model is established by using Delaunay triangulation with the height of discrete points, and then the coordinates and height of each interior point are then calculated. The three-dimensional terrain reconstruction is carried out in PDMS (Plant Design Management System),through which the method described in this article has been proved to be efficient and precise.
